摘要： The invention relates to a radiation detector apparatus (10) with an array (12) of detector pixels. Each pixel (20) of the detector comprises a photogate electrode (21) under which electrical charges produced by incident radiation (v, X) are collected. The change of these charges gives rise to displacement currents in photogate lines (32) connected to the photogate electrodes (21) which may be monitored by current sensors (40). Thus the charges collected by all photogate electrodes (21) connected to a photogate line (32) can be measured during an ongoing exposure, allowing for advanced dose control methods of the illumination.

摘要： The invention relates to a method of reading out the sensor elements of a sensor (1) with a matrix of light-sensitive or X-ray-sensitive sensor elements (S1,2; S1,2 . . . ) which are arranged in rows and columns and generate charges in dependence on the incident quantity of radiation, the switches (3) of the relevant sensor elements being activated via address lines (4, . . . , 8, . . . ) and the charges of the respective activated sensor elements being drained via read-out lines (9, 10, 11, . . . ) so as to be processed further by way of amplifiers (14, . . . , 18, . . . ) and transfer means (19). The invention also relates to a corresponding sensor as well as to an X-ray examination apparatus which includes an X-ray source for emitting an X-ray beam for irradiating an object in order to form an X-ray image, as well as a detector for generating an electrical image signal from said X-ray image. Despite the small incident X-ray doses, adequate amounts of charge, and hence electrical signals, are provided so as to form the image in that ingoing address lines (4, . . . , 8, . . . ) are selectably connected, by way of individually controllable switch elements (27, . . . , 30, . . . ) and by means of a switching operation, to each time the respective next address line and the sensor elements of at least two neighboring lines are activated by means of one ingoing signal, and corresponding outgoing read-out lines (9, . . . , 13, . . . ) are selectably connected, by way of individually controllable switch elements (31, . . . , 34, . . . ) and by means of a switching operation, to the respective next read-out line in such a manner that the charge signals read out from the activated sensor elements of at least two neighboring columns are combined so as to form one output signal.

摘要： The invention relates to an addressing circuit for an array arrangement (100) of electronic units (101), which may be, for example, pixels of an X-ray detector. Every pixel (101) is connected to a spatially adjacent shift register (110), the shift registers (110) being connected in turn column-wise in series and also being connected to a common clock line (111,114). A trigger signal fed via an external trigger line (113) is passed by the shift registers (110) from row to row for every clock signal on the clock lines (111,114). In this process, triggered shift registers (110) activate the associate pixels (101) so that they can be read out via read-out lines (105) that extend column-wise.
